To alt-abme may concern:

Be it known that I, J oHN Louis VViLnn'iM-l` "above the connecting linlrsshown in Fig. 12.

BACH, a citizen of the United States, resid ingat` Baltimore, in the State of Maryland, havel invented certain new and usefullmprovements in Baling Machines; and I do hereby 'declareQthe following' to'be a full,

` clear,.'and exact description of the same,

referencey being had to 'the accompanying drawings, forming part of this specification. This invention relates to baking machines in'general and particularly to -'baking macliines for making small pieces of pastry.

ln-.the Specific embodim(mt illustrated here.;

in the invention is shown as appliedfto a machine for baking ice cream cones.

Tlieprincipal object of the present in-V vention lis to 'improve vand simplify gen- .erallytlie various 'mechanisms of present pastry backing machines with a view to securing a greater output of the machine as well as to lessen the cost of baking and to" avoid as fares possible anyneed for vmanual controloi any part of the mechanism.

Fig. 23 `is an elevation 'of the mold closy ing mechanism: 1

'controlling 'the passage of cones to the conveyor belt The machine 'ci'sists generally of a re- .y

and the feeding and ejectingmeans.

Tlie stationary'frame includes a plurality of radial stoolsl 10 secured'togetlier by the arcuate segments 11 which .form the outer stationary .ring-120i the machine and by the ring 14 which .may be `an integral annular amember'g but preferably 'is composed of a plurality jot similar segments 1'5 as shown.

I The rotatingmemlbei is ,fan Lannular structilresupported on'anoiiter ring 16 and an inner-ring 17, the' outer ringr 16 resting upon rollers 18 carried Eby the stoolslO and the innerV ring beingzsiipported by similar rollers 19' :and being guided by the rollers'20A l rotatably mounted on vertical studs 21 carried "by the stationary inner ring 14 midway between each stool,' the rollers 19y being pref- The purpose ofitherollers 20 is` to correctly center the revolvingfmember'or car.

rier on the stationary annular -frame yWhile at. the a same ti'me permitting free expansion changes.

f The twoconcentricfrings 16 .and 17 of' the'- revolving carrier'V are connected' together by a plurality of radial `members 22- which` carry betweenv tliemi 'the outer and inner when the machine is heated, the rollers 18 Sand 1Q-,being fairly' vwide to accommodate the increase in diameter due to temperature l 'm` vFig.' 24 is an elevation ofthe gate forf" plates 23 and 24 which guide and support the mold sections 25 and 26.

similar cooperating plates 25 and 26 having a plurality of registering cavities 27, prefcrably six in number, for forming the cones these sections being operated toward and away from each other by means of the three cam lugs 28 on each of the two crank shafts 30 journaled in the end plates 23 and 24, projecting entirely through the former and receiving on their extended ends the hub portions 3l of the crank arms 32 through` which the crank shafts 30 receive their motion to close the two mold sections by dii'ectl contact of the cam lugs with the mold pieces themselves, and to open the mold by contact of the rod 33 carried 'by the vthree cam lugs mold section.

The crank arms 32 lare connected to the vertically moving cross head 36 by means of the links 37 so that as the cross headv is lowered the mold is closed and as the cross head 36 is elevated the crank arm will lcause, the two sections to separate. In certain machines I prefer to close the molds by raising the cross head but this is a mere obvious reversal of parts and is therefore not illustrated. The cross head 36 carries at its 'lower end a roller 39- and at its upper end is narrow and bent as at 40 to fit in the slot I 41 between the two parallel guides 42 inounted ,the flanged roller 44 on each of the outer plates 23 in which s lot of the cross head36 moves.

The slot 4l 'is enlarged at 45 to allow for lateral play so that whenthe` flanged roller 44 reaches its lowest 4point it-may be moved laterally in case that one of thetwo mold sections has entirely closed Wliil e the other has not quite reached mid-position. This feature has been thoroughly .tested and has addedmaterially to the smooth action of the device, and effects accurate position closure of the molds. Y

' It has been found preferable to have pins such as 46 on the inner sideofthe plates 23 and 24 so that neither of the two-mold 'sections can pass center or mid-position, this rendering necessary some method for insuring that one ineld's'ection `may close after the other in case one of them is somewhat worn and fails to reach center at the same moment as its companion piece.

The mold sections are locked in the closed position by the arrangement of links and cranks as shown or may-be yieldingly held closed by means of a trackway 50 composed of a plurality of segments 51 which bear in turn against the roller 39 which passes beneath this trackway as best seen'in Fig. 3. On the base of the machine, formed by the radial stools, is'secured a plate or cylinder which is-lprovided with a plurality of `such 54 in eachof the segment-s 51 of the track,

thus drawing the segments close to the cylindrical plate or ring 52 and while preventing lateral movement leaves the segments of the track free to move up and Idownsave for the pressure exerted by the springs 56 here illustratecl as compression springs mounted on a headed bolt 57. passino freely through an angle iron 58 carried bby the radial stools and pivotally connected to the lever 59which is pivoted to the curved'angle iron ll which forms the outer stationary ring l2of the machine.

The amount of pressure exerted by the spring 56 on the segmental track 50 may be altered by manipulation of the lock nut 6l 'and threadingthe bolt 57 into and out of 28' with tl1e`two strips 34 secured to eachl the socket member 62.. It hasv been found unnecessary to provide a duplicate trackway as the trackway 50 on the opposite side of the mold sections due to the fact that the shafts 30 extend through both end plates of the mold and seem in practice to close the distant ends of the mold sections as tightly as the ends 'of the molds nearest the track.

The mechanism for opening the mold sec-A tions is best seen'in'F ig. 8. The shaft- 65 carries a cam cylinder 66 havinga cam slot 67 in its upper portion. Inthis slot travels a roller 68' on the endof`a bellcrank lever 69 connected by link 70 to a second bell-crank lever 7l which lies in the lpath' of the roller 39 on the cross head 36. 'Upon actuation of the roller 68 by movement of the cam 66I it will also be noted that -tlie opening mechanism may be operated either while theinoldv4 carrier is still or is inoving.- f: The cores 75 which form the inner shape of the.pastry in accordance With theusual; practice are S125 in number and are mounted-f on .a horizontal brac-liet or core holder 76 which is integral with, or preferably secured to, the relatively long vertical slide bars 77 which slide vertically in a slot 78 formed.

in the back plates 24 ofA the mold sections. To insure `absolute registry of the brackets or core holders 76 a pair? of rollers 79 are mounted inthe opposite plate-23 of the mold and guide same to correct posit-ion.

At the lower end of each slide bar. 7 7 is a roller 82 preferably carried on a. stud 83..

thisroller being operated by a trackway 8l forn'led of four portions, respectively, an elerating portcn 85, a lowering .poitioii`-86, a reciprocating portion 87, and a pressure portion 88, the latter being quite similar to the trackway 50 for yieldingly holding the mold sections closed,

d'7 t the distant from the 4slide bar 77 vthe core holders` 7 6 each carry a; roller 88 anism will be described in a later paragraph.

After the molds have been filled the cores 'are lowered by engagement of the roller 82 with the downwardly inclined double track 86 which, however, does not permit the, cores to descend to their lowermostposition but nearly thereto. v v The roller 82, next passesfbetwee'n the track portions "87 which aref scalloped to form a zigzag path causing the cores to Vraise and lower'a number of times thus per-y mitting escape of the steam generated in the batter by the-hot molds. It has been found that if the cores descend to their lowermost point without this reciprocation toallw for the escape of the steam, Vthe walls" of the cones are frequently made thin, and otherwise imperfect conesare sometimes formed.

'.The roller 82 next passes to the `pressure portion 88 ofthe track, this portion as stated being formed of anumberof rhomboidal segments 51 each secured to a cylinder 52 by collared studs 53- passing through slots 54 in. the .segments andbeing secured to the cylinder or ring 52 thus permitting freev movement 0f Athe segments up and down while preventing all lateral movement'. TAs in the track 50 each ofthe segments 51 of the-trackwa-y 188 arelpressed down by two,

independent levers 59 the free end of which bears. on the top edge` of the segment 51 while the other end is attached to a spring 56 giving a pressure which is adjustable to the requirements of .the machine by adjusting thevbolts 57. 1

,Since leach of the 4springs are separately adjustable it -is possible to apply .any desired pressurel at any portion of the baking period and if .desired the pressure instead of being controlledby, a trackway substantially idenuniformthroughout vthe Ientire pressure portion of the track, maybe adJusted so aS tojbe gradually increasing or gradually decreasingas maybe.` desired.. The roller 88,v

as previously stated,passes througl1,a11d isv tical lwith the ytrackway `iust mentioned.

. `The feeding mechanismis. shown in Figs. 2 'and 10.` The feedV box 95 in its simplest form @takes batter by gravity from the pipe 96; which leads down yfrom the batter supplyv Y tank` 971. Itis preferab1e,'however, that the batterfshall be supplied under constant; presj sure and iin.- the prfeled .constipation the vbatter isfed-by a pump 99 tothe pipe 100 which leads to an opening 101u in a small chamber 101 having a check-valve 102 at one entrance'. thereof and having a spring pressed valve 103s at the top to permit batter to escape back to the pipe through the by-pass 105 when a4 definite pressure has been reached'in the n ain chamber 106 of the feed box. A second check valve v107 controls passageof batter from the small red -ceiving chamber 101 to the main chamber 106 of the feed box.' a Within the cylindrical bore 109 of the feed box 95 is a valve 111 which has a cylindrical portion 112 to close the orifices 113 through which the batteris-discharged into the cavities of each of the molds. The valve 111 is secured to a shaft 114 preferably by having the engaging portion 115 of the shaft non-i circular, .oblongfor example, and having the valve arms 117 of corresponding4 shape* 1 but allowing considerable play orl up anddown movement' so that as the valve wears,r

it will still` give a water tightjoint, being constantly urged towards the lowerportion of the feedbox in which is located ythe opening 113 by' means pf a plurality of springs 120 attachedto the underside jof the feed 1 box shaft 114 and pressing against the lower]A faces lof the rectangular openings in they valve arms thus` forcing the valve against vthe seat part of -the feeding box; i -4 Y. i

lllr'isijournaledy` f l 1n the removable. end 122 ofthe feed bex 95- m0.

The 4valve stemor shaft and passesthrough the pump end 'head 123 and through` agland'121to` prevent leakage.

At its free endthe stem 11st` carriesla lever- 126 forming at its upper part la cam 12T- i havingl an abrupt shoulder. or hook.. 128*` which engages the long pawl `130 adjustablyf connected tothe ylowerarm 132 of thebell-` crank leverk 13/1`Inounted on the shaft 135..

The lower crankglikelarm V136'o-f-"the lever j 126is pivoted to a rod138 slidably mounted in a depending lug 189Vv whichy also serves as a stop-for thespring .140 wh'ich'tends at all times to close the valve 111-.,

As the pawl reciprocates to lthe tleft, as l,

shown in Figa-10," it rides -up'the cam surface k127 and finally engages the .hook128 thereby opening the ,valve '111 .against thel pressure of the spring 140 On continuedoscillation ofthe shaft anadjustablcscrew 1.43 on the pawl 130 engages the 'cam surface 127 and finally lifts the pointed end 14a of fthe pawl 130 out .of'contact with thc -hook 128 and allows `the spring 140 to -close' the valve' I 111 with f sharp'yand almost'k'nife-likc blow,

thus insuring an extremelyaccuratej regulation of the supply` of batterto the-molds.

The stop" screw .'146isfadjustable -as are the `screws 141-3 and148each"of thesel three being provided `with .lock nuts to insure against* them workingloos'e. "By 'means of thesev -lovcr 177 hv means of the conneetine' link it is somewhat preferable to use the forced pressure through the plunger pump 99. As previously stated this pump is operated from the shaft shown to the right ofiFig. 10

lwhich shaft is driven from the main shaft by gearing of usual and well known type including the bevel gear (see Fig. 6) on shaft 151 which is connected to shaft 152 by means of a plurality ot' sprocket and chain connections. The shaft 152 carries at one end a crank disk 153 to which is pivoted the connecting rod 154 which is pivoted at its upper end to a crank 155 on theshaft 135.

The ejecting mechanism is best shown 'in Figs. 8 and 9. The bracket 160 carries a hollow-box 161suspended by means ot a plurality ot bolts 162 each surrounded by a spring .163 to hold the box spaced in the bracket.

On the lower face of thehollow box and communicating with'the chamber therein are six hollow plugs 164 intended to steady the baked conesl when the molds are opened, these plugs each being provided with a num- -ber of air holes 166 to allow for escape of compressed air delivered to the hollowbox 161 through the pipe 167 `from a source of compressed air (not shown) so that this air ejects the cones should they have a tendency to stick to the cones. Surrounding each plug 164 is an annular cutter 16S adapted to cut the excess batter from each cone separatingv the cones at this time from one another. lvlnle. the machine 1s shown as baking six cones to a mold it is obvious that any other number of .cones may be baked.

yMovement ot the bracket is accomplishedv through the cam 66 which in addition to the previously mentioned groove 67 has a lower cam channel 173' in which travels a roller 174 mounted on one end of the bell crank lever 175 pivoted tothe frame as at 176 and connected to a second bell crank 178. The free end of the lever 177 is provided with a slot 180 which receives a pin 181 on heslide 182 the latter heilig secured at its upper end to the bracket 160. The slide 182, the bracket 160, and the associated mechanisms are balanced by a counterweight 183 'adjustably mounted on a pivoted arm 184: carried by the frame work.

The supply of compressed air to the plugs 164 is controlled by a spring closed valve 185 which is opened by means of the rod 186 pvoted. to. the lever t187 -themovement ved arm or striker clears adapted to of which is controlled by the disk. cam 188 keyed to the top of the shaft 65. The pivotthe opened molds of any cones that might have lodged themselves between the molds due to the ejection operations not properly functioning. Said arm 190 is pivoted at 191 andis rocked up and down on its pivot by an arm 192 pivoted to it at 193 and made fast to cavities of each mold, and are brought torest, point down, against the hinged gates 201 pivoted to the frame as at 202 and each pivotally connected to a eooperatinglink 203 which in turn is pivoted to an arcuate arm pivoted as at 205 to a stationary portion of the structure.

The conveyor belt 207 which passes over the cylinder molds and passes beneath each of the, six hinged gates operating them in turn by means of a plurality of spaced trip pers 211 operate with the hinged gates one at Ia time in regular order as soon as six .or twelve cones have been received inl pulley 209 is wider than the y the chute controlled by such gate. As best 'shown in Fi'gf? the trippers 211 strike the arcuate arms lying in fits path throwing the hinged gates to the left as shown in that ligure and discharging'the six or twelve stacked cones to the discharge belt.

The annular revolving member carrying the mold sections is provided with an annular racky 215 on the inner face of the inner ring ofthe revolving carrier. power for driving the machine is preferably furnished byan electric motor 216 which The i drives the main vertical drive shaft 217' 'carrying at its upper end a roller 218 which drives the parallel` auxiliary means of a Geneva. wheel 221.

The auxiliary shaft 220 carries at its up-v per end a drive pinion 222 which meshes with the annular rack 215 carried by the revolving `frame thus giving the revolving carrier an intermittent movement while the main drive shaft 217 andthe mechanism connect-ed therewith are constantlyin motion. f

The molds are preferably heated on their tops by means of gas delivered to jets 225 carried directly by the upper gas pipe 226 which pipe is' supported by the curved brackets 227 bolted to the upper standards 228 of the radial stools and are heated on their lower surfaces by a similar arrangement of parts' consisting diets-23() connected to the lower gas pipe-237 which latter is supported by the posts 232 secured tothe lower central' seats'233 onvvthe radial stools 110. l f i y The4 tripper plate 2401.(,seefi171g .V 7.) is .an
